rnin'rme STAMP.

Application filed November 20, 1925. same No../O,2B3.

This invention relates to stamps and particularly to numbering stamps. One object of my invention is to provide a stamp which is simple and cheap to make. Another object is to providea stamp in which the type carrying members may be readily replaced by the user. Another object is to provide a novel stamp disc mount which supports the resilient type carrying members between rigid members which may be assembled and disassembled easily. Another object is to provide type carrying members which are carriedupon a single removable shaft. An other object is to provide atype changing device permanently mounted in the stamp shell. Another object is to provide a type disc mount in which the proper relation between the type carrying disc and the indexing wheels are made certain, and other objects will appear hereinafter from the following specification, the novel features being pointed out in the claims at the end thereof.

Certain features of this stamp are the same as parts of the printing stamp shown in U. S. Patent No. 1,518,415, Speidel, et al., issued December .9, 1924.

Coming now to the drawings, wherein like reference characters: denote like parts throughout: j

Fig. 1 is a side elevation of a stamp constructed in accordance with, and embodying one form of my invention, I v

Fig. 2 is a rear elevation of the stamp shown in Fig. 1; I I Fig. 3 is a side elevation of the indexing member;

Fig 4 is a cross section through a type carrying member assembled to the indexing member; I

Fig. 5 is a side elevation of a type carry ing member; s

Fig. 6 is a section on line 6-6 of Fig. 1; and

Fig. 7 is a perspectiveview of the type supporting washer.

In the illustrated embodiment of my invention, the stamp may consist of a shell or casing 1 which is provided with a top 2 in which there is an opening 3 and downwardly extending arms 4 which are provided with bearings 5 for a shaft 6 upon which the type carrying discs, designated generally as 7, are mounted.

In accordance with my invention, the

Y with the'cut-out 17.

type carrying discs,'here shown as numbering discs, may consist of an annular member 8 having a recessed side 9, a central aperture 10 and an indexing aperture 11. Around the periphery ofthis member are the type members 12. This part is prefergblymadeof resilient material such as rub- Inorder to form a stiff support for memher 8, there is provided an indexing member13 having a hub 14 extending to one side of the indexing Wheel and a short hub 15 extending to the opposite side of the disc. The teeth 16 and the cut-out 17 are engaged by the. springpressed yoke 18 which may be carried by a lever 19 having hubs 20 which are preferably carried by bearings 5, as best shown in Fig. 6. An operating handle 21 may beactuated to change the type carryingv discs. This changing mechanism is similar to that shown in the patent above mentioned. A series of latches 22 (only one being shown) may be mounted upon a shaft 23 and may be pressed by springs 24 attached by screws 25 to the top2 of the easing-into engagement with the teeth 16.

The indexingwheel 13 is provided with an aperture 26. A washer 27, having an outside diameter 28 adapted to fit into the recess9 of the typedisc and having an inside diameter 29 adapted to fit on the end of the hub 14, is provided with a. pin 29. In assembling the type disc 7, a resilient member 8 is placed on the washer with the pin 29 extending through aperture 11 and these two members are then slid on the hub. 1.4. The pin 29 passes into aperture 26 of the indexing wheel. This causes the proper type number to lie in the desired relation The pin 29 merely lies in aperture'26 and is not fastened in this position.

A series of the type members, assembled as above described, may be held between the arms 4 of the stamp shell 1-, and a shaft 6 may be then slid through bearing 5 and through thecentral openings 30 in the hubs 14. g The threaded end 31 of shaft 6 may then be screwed into the tapped opening 32 and the stamp is assembled ready for use.

Thus parts of the stampwhich are used for As will be seen from Fig. 6, when shaft 6 is removed to renew the type-carrying memhere 8, the arms 19 remain with the shell, since they are carried by the bearings 5. Thus only the type discs 7 may be removed from the stamp shell when shaft 6 is withdrawn.

The indexing member 13 and the washer 27 are used repeatedly, the resilient type carrying member 8 being the only part discarded when worn. These may be made inexpensively so that a stamp made in accord ance with my invention may be used for a long time.

I have not shown a handle or mount for my stamp in the drawings. This may be of any desired kind, This stamp is, however, particularly useful in connection with the mount shown in my copending patent application, Serial No. 756,348, for numbering stamp for photographic printing machine, filed December 16, 1924.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a printing stamp, the combination with a casing, of a shaft supported by the casing, a type carrying disc of annular form, an annular indexing member having a hub thereon, adapted to receive the type carrying disc and means for positioning the ,disc relatively tothe type indexing member.

2. In a printing stamp, the combination with a. casing, of a shaft supported by the casing, a type carrying disc of annular form having a perforation therein, annular indexing members adapted to support the type disc, said annular members being adapted to turn on the shaft, an annular plate adapted to engage a. side of the type carrying member, and a pin adapted to locate the type carrying member on the indexing member.

3. A type disc for printing stamps including a resilient type carrying member, a support therefor including a pair of plates, and

. registering means for positioning the disc in a predetermined relation to a supporting plate.

4. A type disc for printing stamps including a rubber type carrying member, an an-.

nular rigid support for the rubber member, and a registering device for locating the rubber member on the rigid support.

5. A type disc for. a printing stamp including a resilient annular type carrying member having a perforation therein, a rigid annular support for the type carrying member including a hub and a relatively rigid flange thereon having an aperture therein and means for registering the type carrying member on the disc including a washer adapted to lie adjacent the type carrying member, said washer carrying a pin adapted to pass through the two apertures.

6. A type disc for a printing stamp including a perforated relatively soft type carrying element having a recess in one side, a relatively stiff annular member having a pin therein, and a perforated indexing wheel the type carrying element being adapted to be positioned on the indexing wheel by means of the pin registering with the perforation in the indexing wheel.
